"WebOrganic chemists probably first experience azeotropes by removing water from a refluxing mixture using a Dean–Stark trap, as with the heterogeneous azeotrope of toluene–water. Most of the azeotropes important to process chemists are minimum-boiling azeotropes, i.e., the boiling point of the mixture is less than the boiling point of any component.
